Micro-EDM-Milling has a strong innovation potential because it can perform accurate and detailed cavies with a high aspect ratio. In this technology, the electrode wear and material removal produced by every discharge is determined by the effective power delivered by the generator during every pulse cycle. High speed electronics make now possible the statistical analysis of sparks distributions in real time during the machining but also the measurement and modulation of the characteristics of every spark-discharge. It is now possible to measure and control in real-time the electrode wear and the material removal with extreme accuracy. Our “Smart EDM Generator” has the functions of voltage measurement, spark analysis and process control. It can count the sparks and classified them, control the electro-erosion process and calculate the wear of the electrode. The statistical distribution of the sparks and other parameters can be acquired by the CNC-PC from a direct Ethernet link and be visualized on a specific HMI.
